The ReadyDATA supports a new, proprietary RAID architecture that is both flexible and easy 
to administer. This new architecture is based on the Zettabyte File System (ZFS), allowing 
you to configure different RAID levels for different volumes on the same platform.

Volume and RAID level are tied together on the ReadyDATA in the following ways:

You can select the RAID level for a volume only when you create the volume. After you 
create a volume, you cannot change the RAID level. 

When you create a volume, you select the disks that participate in the RAID set. You can 
select from the following RAID levels: RAID 0, RAID 1, RAID 5, RAID 6, or RAID 10. You 
can add more disks to a volume, but in the process of doing so, you cannot change the 
RAID level. A single exception exists: When you expand a RAID 1 volume, the RAID level 
is automatically upgraded to RAID 10.

RAID levels are indicated onscreen as follows:

New RAID sets. A new RAID set is indicated with a plus sign: RAID 0+, RAID 1+, 
RAID

 

5+, and RAID 6+. The exception is RAID 10, which is indicated with a plus sign and 

a zero: RAID 1+0.

An expanded RAID 0 set is indicated in the same way as a new RAID set: RAID 0+.

An expanded RAID 1 set is indicated with a plus sign and a zero, and becomes in fact 

a RAID

 

10 set: RAID 1+0.

Expanded RAID 5 and RAID 6 set indicated with a plus sign, a zero, and an 
expansion sequence number that indicates the number of RAID groups that have 
been added:

RAID 5+0, nx

RAID 6+0, nx

For example, a RAID 6 set expanded twice by the addition of two RAID groups goes 
from RAID 6+ to RAID

 

6+0,

 

2x, and then to RAID 6+0, 3x.

An expanded RAID 10 set is indicated in the same way as a new RAID 10 set: 

RAID

 

1+0.
